fix: Fix setup bugs, add SteamOS desktop look and LED driver, split into modules

- Fix session switching: sync bridge only edits [Autologin], sync service no longer hits systemd's start limit, re-runs don't duplicate settings - Make the Return to Gaming Mode shortcut work without a password prompt - Steam desktop autostart only runs in Plasma, not inside gamescope - Vapor theme: fix install path, wallpaper, icon and color scheme; take over Valve's SteamOS defaults, GTK theme, panel layout and dark mode; always fetch the newest steamdeck-kde-presets with checksum verification - Steam Machine: install kernel headers and build/load the leds-valve driver reliably; ask before installing OpenRGB - Split the script into lib/ modules per responsibility - Rewrite README for end users with a technical details section; add AGENTS.md
